Every ginkgo callback should return immediately when a timeout occurs or the
test run manually gets aborted with CTRL-C. To do that, they must take a ctx
parameter and pass it through to all code which might block.
This is a first automated step towards that: the additional parameter got added
with
sed -i 's/\(framework.ConformanceIt\|ginkgo.It\)\(.*\)func() {$/\1\2func(ctx context.Context) {/' \
$(git grep -l -e framework.ConformanceIt -e ginkgo.It )
$GOPATH/bin/goimports -w $(git status | grep modified: | sed -e 's/.* //')
log_test.go was left unchanged.

// This test must run [Serial] due to the impact of running other parallel
|
|
// tests can have on its performance. Each test that follows the common
|
|
// test framework follows this pattern:
|
|
// 1. Create a Namespace
|
|
// 2. Do work that generates content in that namespace
|
|
// 3. Delete a Namespace
|
|
//
|
|
// Creation of a Namespace is non-trivial since it requires waiting for a
|
|
// ServiceAccount to be generated.
|
|
// Deletion of a Namespace is non-trivial and performance intensive since
|
|
// its an orchestrated process. The controller that handles deletion must
|
|
// query the namespace for all existing content, and then delete each piece
|
|
// of content in turn. As the API surface grows to add more KIND objects
|
|
// that could exist in a Namespace, the number of calls that the namespace
|
|
// controller must orchestrate grows since it must LIST, DELETE (1x1) each
|
|
// KIND.
|
|
// There is work underway to improve this, but it's
|
|
// most likely not going to get significantly better until etcd v3.
|
|
// Going back to this test, this test generates 100 Namespace objects, and then
|
|
// rapidly deletes all of them. This causes the NamespaceController to observe
|
|
// and attempt to process a large number of deletes concurrently. In effect,
|
|
// it's like running 100 traditional e2e tests in parallel. If the namespace
|
|
// controller orchestrating deletes is slowed down deleting another test's
|
|
// content then this test may fail. Since the goal of this test is to soak
|
|
// Namespace creation, and soak Namespace deletion, its not appropriate to
|
|
// further soak the cluster with other parallel Namespace deletion activities
|
|
// that each have a variable amount of content in the associated Namespace.
|
|
// When run in [Serial] this test appears to delete Namespace objects at a
|
|
// rate of approximately 1 per second.
